The two-way thrust angular contact ball bearing is mainly used to support the precision spindle of the machine tool, and the two-way thrust angular contact ball bearing is directly mounted against the double-row cylindrical roller bearing with a taper hole. Two-way thrust angular contact ball bearings are detachable. They are composed of components that are not interchangeable with other identical bearing components. Basic type :2344 series, 2347 series and 2349 series two-way thrust angular contact ball bearings nominal outside diameter and NN30 series and NNU49 series of cylindrical roller bearings the same, if the two-way thrust angular contact ball bearings and double row cylindrical roller bearings journal matching surface is processed in a fixed loading card, The outer diameter tolerance of the two-way thrust angular contact ball bearing should naturally be a clearance fit. Two-way thrust angular contact ball bearings have a contact Angle of 60°, so they have a large axial load capacity and stiffness.
